BIRNS Emergency Light Fixture-LED Seismic Testing
His video shows BIRNS Emergency Light Fixture-LEDs (ELF-LEDs) during IEEE-344 seismic qualification testing at the National Technical Systems facility. This demanding test sequence uses a tri-axial acceleration table delivering the equivalent of a seismic event at 10Gs of force in the x, y and z axes.
BIRNS ELF-LEDs are advanced, seismically qualified nuclear grade lighting systems that provide 24-40 hours of standby illumination in the event of loss of AC power, which is 3 to 5 times longer than required by the NRC. These rugged, CE marked, RoHS compliant systems have a lamp life of 50,000 hours, and an 11 W power draw.
